Magnesium Fluorosilicate
What is Magnesium Fluorosilicate?
Magnesium fluorosilicate is an inorganic compound, a salt formed from magnesium and fluorosilicic acid, appearing as a white, water-soluble powder. Primarily found in oral care cosmetics like toothpastes and mouthwashes, it serves as a fluoride-releasing agent. Upon dissolution in saliva or water, it dissociates to provide fluoride ions that interact with tooth surfaces, bolstering enamel integrity against bacterial acids. Its mechanism also disrupts bacterial attachment to teeth, curbing plaque formation without abrasive particles. This makes it suitable for formulations aimed at daily oral maintenance. Regulatory databases list it for restricted use in rinse-off oral products at controlled levels to balance function and safety, distinguishing it from direct abrasives or sweeteners in hygiene routines.
